Which is not the quadratic inequality?

A.

Step-by-step explanation:

A quadratic inequality looks like a quadratic equation, but with signs

<, >, ≤, or ≥

instead of sign =

You are given one equation (the first one, because the sign is =) and two inequalities (the last two beacause the signs are < and > respectively).

Thus, correct option is A,

is not a quadratic inequality (it is a quadratic equation)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!
